I got 5,6 and 7 Let us call our integers: n n+1 n+2 we get: 4n=(n+2)+13 rearrange and solve for n: 4n-n=15 3n=15 n=15/3=5 so the three integers are: 5,6 and 7

Because the interhalogen compound and the Noble gas compound are more stable energetically than the individual elements. The interhalogen anion, ICl_2^-, is an analogue of I_3^-. On the other hand …

Sep 20, 2017 · (df)/ (dx)=-2xx10^41/x^21 Recall that derivative of x^n is nx^ (n-1) hence derivative of x^ (-20) is -20x^ (-21)=-20/x^21 As f (x)= (x/100)^ (-20)=1/100^ (-20)xx x ...

See below! :) Examples of phase changes could be: solid to liquid: butter melting, ice melting liquid to solid: freezing water into ice cubes, when molten metals harden (ex. steel) liquid to gas: boiling …

0.33 "mol C"_6"H"_12"O"_6 We're asked to find the number of moles in 60 "g" glucose, "C"_6"H"_12"O"_6. To do this, we can use the molar mass of glucose, calculated to ...
